Again, I have no experience with the reverse limb bows. My crossbow is a horton that's approaching 20 years old now. So it's heavy, wide, and probably slow by todays standards. Still kills deer just fine. But I honestly would not want to carry it on an elk hunt.
When I do finally upgrade(Which won't be for another few years when my kids are ready to start hunting deer with me, I rarely use the crossbow currently but will start my kids out on one when they are ready.) I will be seriously looking into the reverse limb bows.
